What is one advantage of using C++ code for the Arduino platform?
This is an example of a very specific question you may be asked during an interview for a firmware engineer job. While you cannot be aware of all the interviewer's questions, you can narrow the field by reviewing the job description and learning more about the company's operations. This will provide you with specific information related to the work you will be doing and help you focus your preparation on the most likely questions you will be asked.
"One of the advantages of using C code for the Arduino platform is that it enables you to use classes. This simplifies the programming and also makes the firmware perform better. It also allows for the use of virtual functions. An advantage of this is that it broadens the function of the firmware and allows it to handle many different types of operations. An example of this is the print base class. When invoked, it customizes the print methods to specific types of outputs."
